Publication number: 20230260102Abstract: An object of the present invention is to extract image defects from a test image for each type by a simple process. A processor (80) generates a first preprocessed image and a second preprocessed image by executing a main filter process with each of a horizontal direction and a vertical direction of the test image used as a processing direction. The main filter process is a process of converting the pixel value of each pixel of interest sequentially selected from the test image into a converted value obtained by a process of emphasizing the difference between the pixel values of an area of interest and the pixel values of two adjacent areas. The processor (80) extracts, as the image defects, a first singular part that is present in the first preprocessed image and is not common to both images, a second singular part that is present in the second preprocessed image and is not common to both images, and a third singular part that is common to both images.Type: ApplicationFiled: December 22, 2021Publication date: August 17, 2023Inventors: Takuya MIYAMOTO, Kazunori TANAKA, Kanako MORIMOTO, Koji SATO, Rui HAMABE
